Product Detail
FFKM O-ring is a circular seal made of perfluoroelastomer compound, with a higher fluorine content than FKM fluoroelastomer. FFKM O-rings work like any O-ring, sealing two or more parts at the interface.
KALFLUO® 1620 has excellent resistance to chemical corrosion, organic acid, inorganic acid, alkali, ester, ether, ketone, aldehyde, superheated water and steam. The maximum operating temperature is 230 °C. It can be made into O-ring, diaphragm, gasket, rubber strip, rubber plate and customized products.
FFKM O-ring is an ideal choice for harsh chemical environments. Due to its specific characteristics, FFKM has many potential applications in various industries.
